Housing cooperatives are facing challenges like increasing mobility and cooperative banks challenges like stricter regulatory requirements. This diminishes their ability to create MemberValue. Therefore, a research project was initiated with the purpose of analysing cooperation between housing cooperatives and cooperative banks as an instrument for positively influencing the MemberValue. This paper summarises the most important results of this research project. It presents criteria for the eval-uation of options of cooperation, empirical findings on characteristics of this kind of cooperation and tools for its successful management.
